MECHANISM FOR TRANSMISSION OF VARYING POWER LOADS Russian patent published in 1999 - IPC

FIELD: mechanical device used for realization of energy intensive operations at increasing loads. SUBSTANCE: mechanism includes crank, connecting rod, rocker arm and rack articulated together. Output unit carrying the working member is connected with rocker arm. Length of units of mechanism satisfy the following expression: (λ₁+λ₂)²+λ23

= 1,, where λ₁,, λ₂, and λ₃ are relative lengths of crank, connecting rod and rocker arm. According to this expression, maximum magnitude of transfer angle is ensured at boundary at working and idle stroke intervals; minimum transfer angle is obtained at idle stroke interval. EFFECT: enhanced efficiency in transfer of varying power loads increasing from beginning to end of working stroke. 2 cl, 2 dwg
